Exposure to iodine may cause some of the following in hypersensitive people: 1  rash (contact dermatitis) 2  hives (when ingested)  anaphylaxis, or a severe life-threatening allergic reaction (very rarely)
Use heat to sooth the earache. Heat can bring quick pain relief. Apply a warm compress over the painful ear. You can make a warm compress from a washcloth dipped in hot water and wrung out, or from a hot water bottle or heat pack purchased at a pharmacy. Do not make it hot enough to scald the skin.
1 If the pain is severe and doesn't subside with a pill or two, go to your doctor. If you have other symptoms as well (like fever or dizziness), go see your doctor immediately.  Try Auralgan, a local anesthetic that can be applied directly to the ear canal. Auralgan can be found at any major drugstore or pharmacy.
